- SPARE-TIRE CARRIER.

Continuation of application Serial No.

The present application is a continuation of my application, Serial No.109,678, filed July 17th, 1916. V

The present invention relates more particularly to a metallic tireprotecting casing for housing aspare tire of the demountable rim typeand has for its object the provision of a metallic tire case, which iscapable of supporting rigidly therein a demountable rimmed tire, so that.such tire and attached rim when so supported will be entirely envelopedand protected from the heat of the sun and exhaust gases.

A further object is to so construct the metallic housing that it may beconveniently and demountable rimmed tire to be very easily andconveniently mounted or demounted from its support.

Further objects of the invention are to provide a spare tire carrier ofthis character which is comparatively simple and inexpensive in itsconstruction, which can be mounted upon the vehicle in the usual mannerwithout necessitating any special fixtures, which protects the'tire andalso prevents theft or unauthorized removal thereof, and whlch leavesthe space within the tire unobstructed and available foruse in mountingthe necessary lamps, license tags, direction indicators, or the likeupon the car.

-With these and other objects 1n'v1ew, the invention consists in certainnovel combinations and arrangements of the parts as will more fullyappear as the description proceeds, the novel features thereof beingpointed out in the appended claims.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawings, in whicha Figure 1 is aperspective view of the rear end of an automobile provided with a sparetire carrier constructed in accordance with the invention.

Figure 2 is a rear view of the spare tire carrier with the removablecoverof the annular tire housing in operative positlqn.

Figure 3 is a similar view with the said cover removed. I i

Figure 4 is an enlarged transverse vertical sectional view through thespare tire carrier, showing a spare tire in osition therein.Corresponding and 1i e parts are referred 109,678, filed July 17, 1916.This application 1922. Serial No. 546,947.

filed March 25,

to in the followin description and indicated in all the views of thedrawings by the same reference characters.

Referring to the drawings, which illustrate one possible embodiment ofthe invention, the reference numeral 1 designates a tire supportingbracket ring which is of a suitable size to fit loosely within thedemountable rim 2 upon which the spare tire 3 is mounted. This tiresupporting ring 1 may be held rigidly in posi tion by means of, bracketarms 4 which project from suitable parts of the vehicle body, and havetheir outer ends riveted or otherwise securely connected to the interiorof the ring 1. In Figure 1 the tire supporting ring 1 is shown as heldrigidly in a vertical position at the rear end of an automobile body A,only a fragmentary portion of which is shown.

The demountable rim. 2 is engaged by a series of plates 5 which have aswivel connection with the outer ends of screws 6 threaded withinsuitable openings provided in the tire supporting ring'l and spacedcirare adapted to be engaged by a wrench or spe cial tool for thepurpose of turning the screws to force the plates 5 into engagement withthe demountable rim 2, or move the plates away from the demountable rimto re lease the latter. Jam nuts 7 are threaded upon the screws 6 andare adapted to be turned into a tight engagement with bosses orenlargements 8 upon the ring 1 for the purpose of locking the adjustingscrews 6 in position and preventing them from working loose. With thisconstruction it will be ob vious that within certain limits differentsizes of demountable rims can be mounted upon the ring 1 and properadjustment made for securely engaging and supporting the same.

' the weather. This casing is formed in complemental sections 9 and 10,the rear section 9 being shown as permanently connected to the bracketring 1, while the front section 10 is removable for the purpose ofplacing the spare tire in position or removing it there from. The rearsection 9 may be formed with Mounted upon the tire supporting bracket'cumferentially, thereof. The inner ends of the screws 6 have polygonalheads 6*, which by eliminating the bracket one possible embodiment ofthe an inner annular wall 9, which has a substantially cylindricalformation and fits accu- I d rately upon the bracliet ring 1.

The removable outer section 10 is constructed to extend over the treadportion of the spare tire 8, so that access can be readily had to thetire and a secure grip readily obtained thereon when the section 10 isremoved.

' The edges of this section 10 are formed with annular flanges 10? whichtelescopes within the corresponding edges of the rear section 9, andprovide a tight rain anddustproof joint between the sections when thecover is in operative position. Outwardly projecting annular shoulders11 at the bases of the flanges 10 are arranged to engage the edges ofthe section 9 to'limit the telescoping movement of the flanges 10 withinthe section 9. The inner annular shoulder 11 may be engaged by a seriesof spring latches 12 when the cover 10 is in position, and a handle 13may be applied to the cover for convenience in manipulating the same.

Means is also provided for securely locking the cover 10 in positionupon the back 9, therethe possibility of the spare tire being stolen orremoved by an unauthorized person. At one side of the casing, in thepresent instance at the bottom thereof, the outer flange 10 of theremovable cover section 10 is provided with a pin 14 adapted to fitwithin a corresponding opening in the edge portion of the section 9. Atthe opposite side of the casing the section 10 is provided with a hasp15 adapted to be swung over a staple member or keeper 16 upon the member9, a padlock 17 being applied to the keeper 16 to lock the cover 10 inposition. It will be obvious that the cover cannot be removed untilafter the padlock 17 has been disengaged from the keeper 16, and theftof the tire is thus impossible without breaking or multilatin g thecarrier, which would invariably attract attention and be very risky.

The sheet metal casing avoids the necessity of placing a duck or fabriccover u on the spare tire, such covers being more or essno detrimentaleffect upon the sheet metal ca'sing, and the adjusting screws 6 can beutil1zed to hold the rear section 9 of the sheet metal casmg permanentlyin position upon rin 1. While I have illustrated and describedprinciples of my invention, I WlSh 1t to be understood that annularcover for said casing body,

- porting bracket, a cover for said casin b0 thisis illustrative ratherthan definitive and esire to cover said principles in whatever form theymay be embodied.

Having thus described my invention, I claim:

1. A rigid cylindrical casing adapted to receive and enclose a tiresupported upon a demountable rim, one side of said casingbeingremovable, means for securing said side in applied position andmeans engaging the demountable rim at a plurality of points forimmovably holding the rim and tire supported thereon free from the innersurface of the casing.

2. A carrier for spare tires of the demountable rim type, including anannular rigid casing body of smaller inside diameter than the diameterof said tire rim; means to rigidly secure said casing body to anautomobile, releasable means for holding said rim spaced all around fromsaid casing, a detachable said body and cover forming jointly a tubularannular holder adapted to receive a tire and fastening means fordetachably uniting said cover to said casing body, said tire beingsupported free from engagement with the inner surface of the casing.

3. A closed carrier for spare tires of the demountable character,comprising a supporting bracket, an annular casing body open at thefront and rigidly secured to said su the two forming jointly a tubularhol er for the tire, and adjustable means associated with said bracketfor engaging the rim of a demountable tire and holding it spaced fromrim of a demountable tire and hold it rigid,

said sheet metal casing being formed in complemental front and rearsections, and one of the sections having a cylindrical inner wall whichengages the bracket member, the other section being removable andprovided at its edges with anges which have a telescoping engagementwith the edges of the first mentioned section.

5. A spare tire carrier, including a tire supporting bracket member, anannular sheet metalcasing surrounding the bracket member and enclosinthe tire, means carried by the bracket mem ber adapted to engage the rimof a demountable tire and hold it rigid, said sheet metal casing beingformed in complemental front and rear sections, one of telescopingengagement with the edges of the first mentioned section and latchmembers for holding the two sections'together.

6. A spare tire carrier, including a tire supporting bracket member,vanannular sheet metal casing surrounding the bracket member and enclosingthe tire, means carried by the bracket member adapted to engage the rimof a demountable tire and hold it rigid, said sheet metal casing beingformed in complemental front and rear sections, one of which ispermanently secured to the bracket memher, while the other section isremovable, a hasp member upon one of the sections, and a keeper upon theother section for cooperation with the hasp member to admit of the twosections being lockedtogether.

7. A cylindrical casing for a demountable spare tire, including asupporting bracket member, means cooperating with said bracket memberadapted to engage the rim of a demountable rimmed tire to hold the samein rigidly supported position, an annular sheet metal casing associatedwith said bracket member adapted to house said tire, said sheet metalcasing being formed with front and rear sections, the rear section beingpermanently secured to the bracket member and the front section beingdetachably secured thereto and shaped so as to extend rearwardly beyondthe vertical axis of the supported tire to facilitate and makeconvenient the mounting or removal of the tire from the supportingmember,

In testimony whereof I have aflixed my signature to this specification.
